[Asterisk-Users] 1-800 with FWD

If anyone is using @home and needs help here, they'd best say that
right away. I have no idea what @hole does but 393 is an added dial
prefix that may differ in any install. In fact, one could, if using
FWD to be the default 800 number service, just dial 1800 and have the
dialplan add the *.

393 is a convention, it is not mandatory, unless @hole has imposed it.
